This question has come up _several_ times in the past. We've refused to carry
the Tux-on-ice patch for the following reasons:

 - Due to its size and complexity (distro kernel maintenance becomes harder)
 - Upstream compatibility (changing to TOI means a different set of bugs than
 any other distro, again leading to maintenance issues)
 - It requires its own scripts (IIRC) (again divergence from upstream and
 hence new set of bugs and maintenance issues)

No doubt that TOI has some very nice features that our users would like.
Hopefully Nigel and Rafael can now extract those features from TOI and
integrated them into the upstream kernel.
